Abstract: The item count method allows survey respondents to remain anonymous when reporting a sensitive behavior such as cocaine use. This is accomplished by including the sensitive behavior of interest in a list of other relatively non-stigmatizing behaviors. The respondent reports only number of items in the list in which he/she has engaged, not which behaviors. If the average number of non-stigmatizing behaviors is known for the population, one can estimate the rate of the sensitive behavior for the population by the difference between the average number of behaviors reported for the population including and excluding the stigmatized behavior. A very large test of this methodology (n=70,000 persons) was conducted for the NSDUH in 2001 in order to estimate past year cocaine use. The project involved cognitive laboratory research to determine the number of item count questions that should be included and the topics to be covered by those questions (other than cocaine use). In addition, replications of item count questions were embedded in the questionnaire in order to estimate the response variance associated with the item count methodology. This paper reports on the results of the cognitive testing and the estimates of cocaine use that were obtained from the item count methodology. We also report on the results of the response error analysis which helps to explain the poor results obtained by the method.

Abstract: Tracking individual data on health and fitness has become quite popular and is supposed to support health enhancement and behavior changes. But an individual’s decision to use mHealth technology is not an automatic consequence of providing apps or wearables and research indicates that people often do not engage in long-term use. Therefore, the aim of our study was to investigate individuals’ motivation to use health apps and their reason for quitting usage. Based on the Self-Determination Theory and on a Technology Acceptance Model adopted for health app use, we conducted a panel study covering changes of the individuals’ expectations and evaluations regarding usage of a health app over two months. A high proportion of users discontinued using the app. The reasons for quitting were more closely related to technology related experiences and evaluations than to intrinsic and extrinsic motivations to use health apps for health enhancement.

Abstract: The literature has shown mixed findings on the relationship between justice involvement and utilization of mental health and substance abuse treatment services among adults with mental illnesses or substance use disorders. Moreover, it is unknown how criminal justice involvement may be related to utilization of concurrent mental health and substance use treatment services among dually-diagnosed adults. This study examined whether a history of criminal justice involvement is related to the use of contemporaneous mental health and substance use treatment among adults experiencing mental illness and substance use disorders. Using 2009-2013 pooled data from the National Survey on Drug Use and Health, patterns of mental health and substance use treatment utilization of 8,740 adults experiencing past-year mental health and substance use disorders were analyzed. Findings suggest that criminal justice referrals and/or mandates are being utilized to effect receipt of contemporaneous substance abuse and mental health treatment among people with co-occurring disorders. A similar effect of criminal history on substance use treatment was also observed. This latter observation may reflect the possibility that, for individuals with a history of criminal justice involvement, substance use disorders are often identified as the primary treatment diagnosis and/or as contributing to mental health problems.

Abstract: Many devices – for example, a multi-functional printer and a mobile phone – have integrated many distinct functions into one single unit. Previous research in the acceptance studies, specifically studies examining multi-functional devices, continues to examine the adoption of these technologies by applying an overall evaluation. Analyzing different functions separately is important as these functions may be unique. Especially, some individual functions – such as a camera or an mp3 player which is integrated in a mobile phone – are still sold separately. Drawing upon studies on information systems acceptance, this paper analyzes phone, organizer, Internet access, camera, and mp3 player, the five functions, in the PDA. A survey with more than 200 respondents showed that perceived ease of use and perceived usefulness of each function in the PDA can explain about 47 to 67 percent of the variance in usage intention of its function. Implications for manufactures of such a device are discussed.
